Disposable litter for cats or other domestic animals

Abstract

A disposable litter for cats or the like domestic animals, comprising a flat-bottom shallow container having an open top, made of rigid or semirigid material of the waterproof type or made waterproof. The litter also comprises a layer of absorbent material disposed at the bottom of the container and a membrane sealed directly to the container to hold the thick layer of absorbent material as long as desired in position at the bottom of the container. Once removed, the membrane gives access to the layer of absorbent material and thus allows transforming the latter and the container into which the absorbent material rests into a litter for cats or the like domestic animals. Advantageously, the container and the membrane are made of a low-cost material such as cardboard or a moulded plastic material in such a way as to form together a package of the disposable type that may be discarded with the thick layer of absorbent material once the latter is soiled. A moulded cover, having a handle and formed with feeding troughs, may also be provided.
